Well that sure generated a lot of response. At one point I'd asked about how to get the caps off ('97) without mucking up the wheel and was told about this rubber cap that prevents it. Any appropriate tool would work, it's just that the tip fits correctly. Yeah it's not highly durable, I wrapped some blue tape around it... not that it matters much. The main thing is I just didn't want some tire guy going in there with metal on metal because so far the alloys are in pretty good shape so I was going to just take the wheels to the tire place to swap on new tires thus avoiding that plus avoiding overtight lugs plus avoiding them touching anything else. At some point I suppose it may have to go to a shop for work but so far no. I might get alignment checked at some point, but the tires on there now are pretty worn and the wear is very even on them so I don't suspect any alignment issue, plus it drives/brakes straight so alignment is probably good.
There's actually room for storage, at least on the driver side, behind/under the jump seat. I think right now I'm keeping a 12V inflator and a 12V searchlight in there.
I suppose sometime I might want to make sure the spare comes down ok. It looks way simpler on the '97, no key or weird process to turn things and a key.... looks like just the one bolt, I think. I guess they never had a flat, or, had someone else do it, but the spare looks unused. Wrong size, of course - 235/70R15.... that's oem even if you had 265's.
